Microphones
A microphone is a device that converts acoustic power into electric power, sound waves to electrical voltages, then converted into sound waves that are amplified through speakers.
We associate microphones often with the music and the entertainment industry, but the device can be dated back as early as the 1600s when scientists figured out that they could amplify sound.
